Hi WKla , thank you for the explanation the problem is that i dont want to communicate modbus. I want to use ASCI serial RS232. Can you tell me what are the differences between the 232-ADP-MB and the 232-ADP if i understand correctly i must use the RS/RS2 blocks and not the ADPRW for serial communication. Rheinhardt

Yes i have the connector boards inserted. I have configured my Channels to each partnering devices settings. I also have a code section where these settings are being re-defined ( not sure if i have to do this) and then i have the call to my ADPRW block. Should i not use the RS or RS2 blocks? When i EN block nothing happens see configuration and code below. on CH1 i want to send ASCI data RS232 to a 3rd part controller Rheinhardt

FYI, I found the problem is using a seperate send and receive block.After using theFX3FixedBufferPairingUNpassive block all issues were resolved. i misunderstood gambit when he said port initialization as this still gets done by the 3rd part pc. Rheinhardt

Good opinion. Sitting with exactly this problem now.

OK i found something very strange. When i download my settings and do a verify it seems not all parameters are being changed. How can i clear this data to ensure there are no mismatches. I think this might be part of my problem. Unless i completely leave out FX configurtor and do all this setup within the code.?? Attached is my verify screen

Hi Gents, We want to communicate to two RS232 devices. We have procured the following hardware. FX3U with 2 FX3U-232ADP-MB + connectors. We use IEC V7.04 Hardware On CH1 i have a "Master" that writes ASCI Data to a 3rd party controller. On CH2 i have a "Slave" that reads data from a Barcode Scanner. Software. I have configured the two channels under PLC options tabs. I will add the software that defines these parameters within the code. I plan to use ADPRW block to transfer data. 1. Will this Hardware work for this purpose? 2. Does one have to define and program the Channel Data if you have configured it within the development environment? 3. Can i use the Beijer standard function blocks 4. Where can i find more data on the ADPRW command, it is strangely not in my help file. Rheinhardt

Hi Gents, What are my other options to communicate TCP to this computer. can i initialize a send receive ports through code on my side? Rheinhardt

Hi Thank you for the advice. I dont initialize the port communication the 3rd party software initiates this. Do i not have to close this port using programming? Rheinhardt

Hi Gambit , i use the standard initialization block as supplied by Mitsubishi. See attached

Hi Gambit, I have done this setting but it makes no difference the only time i am able to connect properly is after a power down and up. Any other possible ideas /routes. It even happens when i re-initialize the the Ethernet card. Rheinhardt

Hi Gents, I am having the following problem. I hvae a FX3u-Enet module that communicates to a 3rd part pc. Underneath is my config. Initially after power up when i connect to my communication pair both connections are opened(Connection 2 & 3). The problem comes when this connection falls away and then tries to reopen these connection. At first it would only connect to the send connection when i disconnect and reconnect it only connects to the receive connection. I have attached Ethernet diagnostics. The screens are under following conditions. NXAutoConfigure.jpg -- Configuration settings NXAutoConnect.jpg -- Initial connection. Works 100%. Send and Receive NXAutoDisConnect.jpg -- Initial Disconnect from 3 rd party NXAutoConnect2.jpg -- When connecting a second time. Only Receive works. NXAutoConnect3.jpg -- When connecting a 3rd time. Only Send works. Afterwards it toggls between the two and i cannot get both open. I have tried to re-initialize using code but it does not make a difference. Any idea what could be causing this?

HI Gents, Does anybody know where one can download the POU Library for Ethernet communication via TCP. I have downloaded examples from their site but they are all write protected. I have unpassive no procedure. I have managed to open the connection but for the life of me cant get hold of these function blocks. Any help will be appreciated. Rheinhardt

Hi Gents, I came right using the MID functions. Thanks

HI Gents, I am sitting with the following problem. I have a TCP string that i read in the following ASCI IN,ADNASDFREDW00152,200032,N My offset start at D400 where the IN ASCI characters are At D401 i have the following characters ,A I need to move the string ADNASDFREDW00152 to a variable when i use BMOV_E instruction it i get ,ADNASDFREDW00152 which i do not want. Is there a way i can shift the "," out of position so i can have ADNASDFREDW00152 Thanks in Advance Rheinhardt

Thank you Kaare
